Redefining Visual Boundaries | E-link China Launches 4K 60Hz All-in-One HDMI KVM Fiber Extender

One Cable, Infinite Possibilities: World's First 4K KVM Fiber Extender with 10 Integrated Functions Launches

Single-Fiber 4K@60Hz Lossless Video, KVM/Audio/Serial/Network/IR/EDID Support. Breaks the 80km Ultra-Long-Distance Visual Control Barrier

In professional scenarios such as command and control centers, medical operating rooms, large-scale live events, and high-end simulation training, extending ultra-high-resolution video signals along with rich control interfaces over tens or even hundreds of meters has been a core challenge for system integration. Traditional solutions often require deploying multiple cables for different functions, leading to complex wiring, signal interference, and high costs. E-link China officially introduces the revolutionary LNK-4KH-1D1U1E1A1R All-in-One Fiber Extender. This device can simultaneously transmit lossless 4K@60Hz video, KVM keyboard/mouse control, audio, bidirectional RS232/485 serial data, TCP/IP network, and infrared control signals over a single fiber optic cable, truly achieving "one cable for all, zero latency in sight and control," redefining the integration standard for professional AV transmission.
